V2 migration tool - Error in package.json + Improvements

[steffanek]

Error:
After running the migration, there is a need to manually update your package.json file(s) from:

"peerDependencies": {
    "@qwik.dev/core": ">=1.3.1"
  },

to:

"peerDependencies": {
    "@qwik.dev/core": ">=2.0.0-alpha.4"
  },

Improvements:
First:
There is no such import { FunctionComponent } from '@qwik.dev/core/jsx-runtime';
You can directly import { FunctionComponent } from from '@qwik.dev/core';

Second:
There is no such import type { CorrectedToggleEvent } from '@qwik.dev/core';
Instead you can: import { CorrectedToggleEvent } from '@qwik.dev/core/dist/core-internal';

ps. I encountered the following while upgrading @qwik-ui.
